Dioptase with Wulfenite and Mimetite (2018 find)

Item Description

PLEASE NOTE: These specimens were initially reported as coming from the Mpita Mine, but we have subsequently been informed that they are actually from the Ntola Mine. This piece is from a new find in January of 2019. Most collectors love Dioptase, but there aren't that many world localities that produce excellent specimens. We were fortunate to purchase a small parcel of these new specimens from the Mindouli area in Republic of the Congo (Brazzaville). This specimen is notably different from many of the others we've seen in the past as it features both prismatic single trigonal crystals along with somewhat spherical clusters of Dioptase comprising tiny, lustrous, rich emerald green crystals. The largest individual Dioptase crystal measures 7 mm long. Additionally, and most importantly, upon close inspections there are a few spots featuring small brilliant orange, pyramidal Wulfenite crystals along with some incredibly hard to find "balls" of greenish-yellow Mimetite! Wulfenite, Dioptase and Mimetite are rarely found together in nature, and the combination of the orange, yellow and green together is wonderful. Associated underlain micro grey Calcite makes for a nice touch as well. For the most part, the piece is in great shape, but there are some contacts around the periphery where it was removed from the pocket wall. I had a lot of fun looking at this piece under the microscope, and we have photographed it with a CANON MP-E 65 mm macro lens to better illustrate the quality. The rare association of Wulfenite and Mimetites combined with the unusual formation of the Dioptase combined with the fact that Dioptase prices are on the rise makes this a very desirable and eye-catching specimen from this exciting locality in Republic on Congo. Priced in the inventory at $1,250.
